media: staging: ipu3-imgu: Use %pe format specifier

The %pe format specifier is designed to print error pointers. It prints
a symbolic error name (eg. -EINVAL) and it makes the code simpler by
omitting PTR_ERR().

This patch fixes this cocci report:
./ipu3/ipu3.c:534:5-12: WARNING: Consider using %pe to print PTR_ERR()
